.ToaZl whom it may concern: Be it known thatl. Lno Gr. HAASE, :1 01(71-zen of the United States, residing at Pasa dena, in the county of LosAngeles and State ofCalifornia, have invented new and usefulImprovements in Knockdown Concrete Incinerators, of which the followingis a specification.

My object is to make a knock-down concrete incinerator which may bereadily set up in the back yard for burning rubbish, and my inventionconsists of the novel features herein shown, described and claimed.

Figure 1 is a perspective of a knock-down concrete incinerator embodyingthe princl- 1 ples of my invention, and showing the parts set up readyfor use. i i

Fig. 2 is a perspective showing the parts stacked for shipment and readyto be set up. Fig. 3 is a perspective of one of the main members shownin Figs. 1 and 2.

Fig. 4 is a ing member.

Fig. 5 is a fragmentary perspective showing a modified construction. v

The incinerator shown in Fig. 1 consists of a plurality of concreteslabs 1 setedgewise one upon another and sidewise in a perspective ofthe draft opencontinuous circle, there beinga draft opening slab 2incorporated into the incinerator with the slabs 1, a screen 3 over thedraft 1 opening, and a screen 4 over the top.

The main slabs 1 are all alike and each f slab comprises a flat body 5having air open- ;ranged in the form of a casing, vertical the exposedend faces and hinge members 8 ings 6 through the body and notches 7along and 9 extending from the end edges, said hinge members beingofiset relative to each other, so that the inner end face 10 of thehinge member 9 of one slab will fit against the inner end face 11 of thehinge member 8 of the next slab.

The draft opening. slab 2 is similar to the slabs 1 except that a notch12 extends from the lower-end face 11 of the hinge member 8 straighttoward the hinge member 9 and about three-fourths of the distance thusleaving a portion 13 to which the hinge member 9 is attached. Areinforcing rod 14. is embedded into the material of the slab 2 tostrengthen the portion 13.

The slabs 1 and 2 thus constructed are stacked for shipment as shown inFig. 2, the hinge members of one slab fitting in the notches at the endsof the hinge members of an adjacent slab.

In constructing the incinerator shown in 1* 1g. 1, hve slabs l are set111 position to form a row and one slabs is incorporated into the rowthus producing the lower tier 15, then thetier 16 is stacked upon thetier 15,

and thetier 17 stacked uponthe tier 16 and the rods 18 are inserteddownwardly throughtlie hinged members. The heavy wire screen 4 isadapted to rest upon the upper edges of the tier 17 and the heavy screeni 8 is adapted to cover the opening 12.

around so as to make good combustion.

In Flg. l I have shown an incinerator draft through theopenings 6 allthe way hexagonal or six-sided in plan, and in Fig.

5 I haveshown the incinerator octagonal or elght-sided. It is obviousthat the incinerator may be made larger or smaller by using more or lessslabs in a row.

Thus I have produced a knock-down concrete incinerator comprisingrectangular plateshaving mating hinge members so that the plates may beset up in rows and stacked one row upon another edgewise and hinge pinsinserted through the hinge members.

Various changes may be made without departing from the spirit of myinvention as claimed. 1

v I claim: r

1. A knock-down incinerator including a plura'lityof superimposed hingedplates arhinge bearings at opposite edges of each plate in alinemcntwith vertical hinge bear ings on adjacent plates, rods detachablyextending through the alined hinge bearings,

one of the lower plates being provided with u plate in alinement withvertical hinge hearngs on ad acent plates, rods detachably extendingthrough the alined hinge bearings, one of the lower plates. beingprovided with a draft opening, and a screen fitting on the top. of saidcasing.

3. A"knock-down incinerator including a plurality of superimposed hingedplates arranged in the form of a casing, vertical hinge bearings atopposite edges of each plate in alinement with vertical hinge bearingson adjacent plates, rods detachably extending through the alined hingebearings,

one of the lower plates being provided with a draft opening, and ascreen covering said draft opening.

L'A knock-clown incinerator including a plurality of superimposed hingedplates arranged in the form of a casing, vertical hinge bearings atopposite edges of said plates, the hinge bearing at onecdge of eachplate extending from the lower edge of the plate about half its height,the other hinge bearing of each plate extending from its upper edge to apoint about half the height of the plate, the hinge bearing extending'fronithe upper edgeof' each plate resting upon the top of the bearingextending from LEO G.
